Q26 of 90 Page 111

The difference between the ages of two cousins is 10 years. 15 years ago, if the elder one was twice as old as the younger one, find their present ages.

Let the ages of cousins be x years and x - 10 years


According to the question


x - 15 = 2(x - 10 - 15)


By cross multiplication


⇒ x - 15 = 2x - 50


⇒ x = 35


So, cousins are 35 Years and 25 years in age
